Embodiment 1

[0030] Such as Figure 1~5 As shown, a hemostatic clip application system includes a clip body 1, including a pair of elastic clips 11, the tails of the pair of clips 11 are fitted and fixed, the upper part has a bent end 12 facing the other clip 11, and the middle part It is a transition section 13 in which the distance between the two clips 11 gradually increases from the tail to the top, and the end surface of the bent end 12 of the clip 11 is serrated, so that the clip body 1 can effectively stop bleeding after being released;

[0031] The connecting column 6, its upper end is fixedly connected with the tail of the clip body 1 through positioning pins, two groups of grooves 61 are arranged on the side, and the two groups of grooves 61 are distributed up and down along the axis of the connecting column 6, and the lower end is provided with an insertion hole;

[0032] The positioning sleeve 2 is used to fit the connecting column 6 and the clip body 1. Its inner diameter matc...

Embodiment 2

[0042] Such as Figure 7As shown, as an improvement of Embodiment 1, the upper end of the positioning sleeve 2 is also provided with a bending part 21 facing the center line of the positioning sleeve 2, and the bending part 21 is located at the transition section between the two clips 11. 13. When the steel wire 5 is pushed, the bending part 21 can force the clip body 1 to open, so as to avoid the situation that the two clip pieces 11 are not separated.

Embodiment 3

[0044] Such as Figure 8 and 9 As shown, the structure of the fastener 3 and the positioning sleeve 2 in Embodiment 1 is changed as follows: the upper part of the fastener 3 is conical, the lower part is cylindrical, and the joint between the upper part and the lower part is provided with a ring groove 33; The tail of the positioning sleeve 2 is provided with an elastic sheet 25, which is a part of the side wall of the positioning sleeve 2, and its two sides and bottom are separated from the main body of the side wall of the positioning sleeve 2, and the bottom of the elastic sheet 25 has a direction toward The flange 26 in the centerline direction of the positioning sleeve 2, the elastic piece 25 also has a protrusion 27 facing the centerline direction of the positioning sleeve 2, and the fastener 3 and the positioning sleeve 2 cooperate with the flange 26 through the ring groove 33 Snap-on connection. Other structures are the same as in Embodiment 1. When tripping, since ...

Abstract

The invention provides a clamping system for a hemostatic clamp. The clamping system comprises a clamp body, a connecting column, a positioning sleeve, a spring pipe and a steel wire, wherein the clamp body comprises a pair of elastic clamping pieces, the tails of the elastic clamping pieces are fixedly abutted, a transition section is formed between the two elastic clamping pieces, and the distance between the two clamping pieces is gradually increased from the tail ends to the upper parts; the upper end of the connecting column is fixedly connected with the tail of the clamp body, a plurality of grooves are formed in the side surface of the connecting column, and an insertion and connection hole is formed in the lower end of the connecting column; the positioning sleeve is used for sleeving the connecting column and the clamp body, a group of bulges which are matched with the grooves in the connecting column are formed on the inner wall of the positioning sleeve, and a limiting mechanism for preventing the connecting column from sliding out of the positioning sleeve is also arranged at the tail of the positioning sleeve; a clasp is fixedly connected to the upper end of the spring pipe, the clasp can be connected with the positioning sleeve in a clasping manner, and the clasp clasping the positioning sleeve can be unclasped under the effect of the connecting column; the steel wire penetrates through the spring pipe and the clasp to be connected with the connecting column in the positioning sleeve, and is mounted in the insertion and connection hole of the connecting column. In the application, the clamp body is specified to be positioned at the upper part of the clamp body. The clamping system can perform trial operation, parts of the clamping system can be replaced, and partial components can be used repeatedly.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a hemostatic forceps. Background technique [0002] There are many hemostatic forceps products in the prior art, the most common one is the hemostatic forceps product of Boshi Duan Science International Co., Ltd., which has the advantage of using a plastic outer sleeve, and the replacement of the hemostatic forceps does not need to pull out the plastic outer sleeve, and the endoscopic equipment is fully protected. The body can be opened and closed repeatedly, and doctors can perform tentative operations, but the hemostatic forceps are disposable as a whole. If a patient needs multiple clips, multiple sets of products are required, which is expensive; Olympus Medical Co., Ltd. The advantage of hemostatic clamp products is that the chucks can be replaced. If you need to implant multiple chucks, you only need to pull out the product and install the chucks. However, the chucks cannot...
